' the shelf, and at the same time to This invention relates to devicesusually provided for engaging the side edges of the sheets as they areplacedinto position for writing.

Heretofore the side age has been in the form of a ledge turned /up fromthe plate, .the latter provided witlf a claw or hook to fit tightly-uponthe beaded upper edge of the paper shelf, as in the wellknown Underwoodtypewriting machine.

It has been found in practice thatzthese hooks and claws must be sotight, in order to hold the gage roperly upion the letterfeedingcarriage, tffat it is di them along the paper shelf, owing to t eirstrong binding actioni and moreover the shelf becomes scratched andmarred.

The object of this invention is to provide for-convenient and easyattachment and detachment of the gage from the paper shelf and easyadjustment therealong, without any liability of marring the appearanceof rovide a very effective means for holding t e gage in any position.

I According to this invention, a side gage plate is bentup at rightangles from a base plate, which overlies the front face of the papershelf. The upper end of the base plate is curved around the top of theheaded edge. of the shelf, and 'may be provided with a bearing surfaceof felt or soft material, to prevent ma'rring the shelf. The curvedpor-,tion of the plate is extended to form a fingerpiece. A second plate ishinged upon the main plate, and is also extended to form a companionfinger-piece.

Projecting from the second plate is a pair of claws to catch between theedge of the beaded portion of the shelf and the rear face of the shelf.A spring gives the power to grip the shelf.

n the accompanying drawings, Figure 1 is a cross-section of the platenframe of an Underwood typewriting machine, showing how the improved gageis applied to the paper shelf. Fig. 2 is a view similar to Fig.

cult to ad'ust ii, but showing the improvedgage applied 1s a perspectiveto thejia er shelf.--Ei vi ,v shoy ingihe impl huiid gage in an invertposition.

T usual platen 1 and axle 2 are revolubly'lnpunted 'in a'platen frame 3,which ineludes an inclined paper shelf 4, at the rear of'the platen, tosupport the paper during the operation of the mach-ine,t 1e shelf havingits upper edge provided with a rolled or beaded rim 5. I v I u The sidegage device comprises a plate 6, bent up from a bottom plate 7 whichoverlies the front face of the paper shelf 4, the plate 6,

serving to gage the edge of the paper as it is inserted between theshelf and. platen. The

upper end of the late 7 is curved as at 8,;to

- conform with the .eaded end 5 of the shelf 4,

and may be provided with a piece of felt or soft material 9; to preventany marring of the surface of the shelf. v

Extendingdownwardly from the toppertion of the plate 7 are two ears 11,between V which extends a shaft 12. A plate. 1'4has a pair of ears 15,projecting upwardly, by means of which the plate is hinged upon theshaft 12. There are also projecting from theplate 14 two claws 16, whichengage between the edge of the beaded portion 5 of the shelf 4 and therear face of the shelf. It is preferred to separate these claws and formthem so that they will have a binding or wedging action between thebeaded edge and the shelf, to secure a substantial grip, to retain thegage against accidental skewing during the intermittent movement ofthe-typewriter caragainst the rear of the shelf to produce the wedgingor binding action are designated as 16?, and'consist of cars bent upfrom the front edge of the plate 14. continued rearwardly to form afinger piece 17, and cooperates with a fingerpiece 10 extended from thecurved portion 8 of the plate- 7, to form a grip. Springs 13, carried onthe The plate 14 is shaft 12,-ongage the finger piece to cause thefingers 16 to ress against the shelf to hold the gage in p ace, as shownin Fig. 2.

To place the gage on the shelf, the finger pieces ,10 and 17 are pressedtogether as showIr/inFig. 1, to open the jaws of the clip, and the ga eis brought down on. the front faeeof the jielf 4, when the finger )icccsmay bereleased and the springs 13 wili cause the rofki'ng of thegripping member 14 and cause the fingers 16 to wedge themselves betweenany time it is only necessary to press the fingenpi'eces 10 and 17, andwherever desired. held by aresilient justment of which there is notendency to injure the front surface of the shelf.

Having thus described my invention, I claim:

A device of the character described, comprising a plate to besecured,- against the front face of a typewriter shelf and having a partto serve as a paper age, said plate exslide the gage The gage is verysecure y gripping means, the'adtending over the upper er ge of the shelfand having a finger piece, hin ed claws for engaging at the rear of theshelfto hold the gage in place, a spring for forcing said claws intoengagement with the shelf, and a companion ger piece carried by saidclaws. 2. A device of i the character described, comprising a plate tobe secured against the front face of a typewriter shelf and having apart to serve as a paper age, said plate extending over the upper e geof the shelf and having a finger piece, hin ed claws for engaging-at therear of the shelfto hold the gage 1n place, a s'prin for forcing saidclaws into engagement wit the shelf, and a companion is Very convenient,and
